Enabling CDA feature

Current consensus

Enabling CDA feature is a CDA feature capable of promoting cooperation among traffic participants intended to facilitate the performance of actions by road users and road operators that they would otherwise not be able to perform.

Explanation

Note: Unlike supporting CDA feature, enabling CDA features result in a different outcome (e.g., detect occluded object, achieve target lane position, expand ODD, etc.).

  • Example 1: A C-ADS-equipped vehicle detects a pedestrian in a crosswalk and shares information with a second approaching C-ADS-equipped vehicle about the location of a pedestrian in a crosswalk, where the second vehicle may not have the capability to otherwise detect the pedestrian, due to line-of-sight blockage by another vehicle on the road. Based on the shared pedestrian information, the second vehicle is able to plan appropriate maneuvers to ensure all participants’ safety.
  • Example 2: A CDA feature enables coordinated intersection departure by means of an infrastructure device providing C-ADS-equipped vehicles with SPaT information allowing nearby C-ADS-equipped vehicles to coordinate their departure timing and velocity trajectory for enhanced safety and efficiency.
  • Example 3: A CDA feature enables closely coordinated vehicle platooning movements by exchanging information about desired velocity and headway among vehicles.
  • Example 4: A CDA feature enables cooperative merging whereby a subject C-ADS-equipped vehicle uses machine to machinecommunication to request a desired lane position and maneuvers from nearby C-ADS-equipped vehicles, such as slowing down to allow the subject vehicle to move from an on-ramp to a highway. Due to coordinated maneuvers enabled by CDA, merging can be conducted smoothly, without negatively affecting traffic flow.
